This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.

表明：(1)激光熔覆合金层是由过饱和的γ基体相和复杂的六方M_7C_3碳化物相所组成(2)在其他参数不变的情况下，随激光扫描速度的提高，γ基体相过饱和度增大，而析出的碳化物含量减少，因而合金层的硬度升高，耐磨性有所下降；而降低激光的扫描速度，碳化物M_7C_3析出增加，有利于提高合金层的耐磨性、因此碳化物M_7C_3析出量是提高耐磨性的主要因素，而增加基体相γ的过饱和度则是硬度提高的主要因素
